Please work off of the latest Mahout 0.9, most of these issues from Mahout 0.7 have been addressed in later releases.

I've searched the archives and haven't been able to find info on this. I apologize if this is a duplicate question. The cloudera install comes with Mahout 0.7. I've run into a few snags on the first step (chunking the data into pieces). The first was that it couldn't find wikipediaXMLSplitter but I found that substituting org.apache.mahout.text.wikipedia.WikipediaXmlSplitter in the command it got past that error. (just changing the capitalization wasn't enough) However I am now stuck. I'm getting a java.lang.OutOfMemoryError: Java heap space error. I upped MAHOUT_HEAPSIZE to 5000 and am still getting the same error. See the full error here: http://pastebin.com/P5PYuR8U (I added a print statement to the mahout/bin just to confirm that my export of MAHOUT_HEAPSIZE was being successfully detected) I'm wondering whether some other setting is overriding the MAHOUT_HEAPSIZE? One of the hadoop or cloudera specific ones? Does anyone have any experience with this or suggestions? Thank you, Jessie Wright
